3 way cross black connector set

(12 customer reviews)


  • HJ-4 is a 3 way black painted metal joint set that consists of: (x2) H-4, (x2) M6-25B bolts and (x2) M6-N nuts
  • Great option for creating separations while maintaining rigidity on any structure when combined with our 28mm (1-1/16″) pipes with just a 5 mm Allen key
  • This is an ideal choice when you need to create an intersection between two perpendicular pipes
  • E-coated paint for a lasting finish that will stand up to outdoor environments
  • Don’t forget all our joint sets are 100% Re-tinkable!
  • Fits on 3/4″ EMT conduit with the use of a EMT-ADPTR34 for every connection. Select the option to automatically add them to your purchase.
